Hal Finkel 0d252ab8da [DAGCombine] Remove SIGN_EXTEND-related inf-loop ... The patch's author points out that, despite the function's documentation, getSetCCResultType is only used to get the SETCC result type (with one here-removed problematic exception). In one case, getSetCCResultType was being used to get the predicate type to use for a SELECT node, and then SIGN_EXTENDing (or truncating) to get the input predicate to match that type. Unfortunately, this was happening inside visitSIGN_EXTEND, and creating new SIGN_EXTEND nodes was causing an infinite loop. In addition, this behavior was wrong if a target was not using ZeroOrNegativeOneBooleanContent. Lastly, the extension/truncation seems unnecessary here: SELECT is defined as: Select(COND, TRUEVAL, FALSEVAL). If the type of the boolean COND is not i1 then the high bits must conform to getBooleanContents. So here we remove this use of getSetCCResultType and update getSetCCResultType's documentation to reflect its actual uses. Patch by deadal nix! llvm-svn: 219141		2014-10-06 20:19:47 +00:00
